36-year-old Juan Antonio Rosa would receive orders from interested parties through social networking sites and then fulfill them during his shift at Wendy's, according to Assistant U.S. Attorney Tracy Thompson.

The father of two had previously served five years in prison for a state child porn conviction, and started working at the unidentified Wendy's branch in 2010 upon his release.

"I can tell you the San Antonio franchisee has no knowledge of the incident," said Wendy's spokeswoman Andrea Winans. "They have no information or any police report of this incident occurring at a Wendy's there."
